We're excited to announce that Exoscale Scalable Kubernetes Service (SKS) now supports the following Kubernetes versions:

What's New

🔐 User Namespaces Enabled by Default in 1.33.1

Kubernetes 1.33.1 introduces user namespaces as a default feature in SKS. This critical security enhancement provides an extra isolation layer between containers and the host system, helping you run workloads more securely in multi-tenant and zero-trust environments.

User namespaces have been stable since Kubernetes 1.30.0, but with 1.33.1, we're enabling them out of the box.

Action required: To benefit from this security improvement, please upgrade your cluster nodes to version 1.33.1.

🛡️ AppArmor Enforcement Introduced

We've also introduced explicit AppArmor compatibility checks starting with this release.

While AppArmor has been usable in most past SKS versions, a recent regression highlighted the need for stricter validation. We now enforce prerequisites to ensure AppArmor is consistently available across all future Kubernetes versions on SKS.
